How to get ssl/tls certificate from https response in nodejs

I'm implementing a certificate automation service, and I want to verify the certificate is deployed correctly by making a https request after deployment, the https response should bring me the new deployed certificate's info, such as issue date and expires date.

I know this is something part of the socket programming, so I wondered if anyone knows there are some existing packages that I can use.

If there is no such packages, I may go deeper to learn some handshake flows and do it with Socket directly.

Ps: The most closest things I know is when implementing a custom x509 trust manager in JAVA, it do support verifying the certificate from the client side.

The https://www.npmjs.com/package/certnames package inspires me, then I found I can do it with bundled tls module directly, as the certificate is transfered through tls layer, so we don't need to make a http request to get it.

import * as tls from 'tls';

test('test', function (done) {
  let host = 'httpbin.org';
  let socket = tls.connect({
    port:443, 
    host,
    servername: host, // this is required in case the server enabled SNI
  }, () => {
    let x509Certificate = socket.getPeerX509Certificate();

    expect(x509Certificate.subject).toBe('CN=httpbin.org');

    done();
  });
});
